Gedackt

The name stems from the Middle High German word gedact, meaning "capped" or "covered".

The concept of the stopped flute pipe (of which gedackt is a prime example) is almost as old as organ construction.

They are occasionally square, but much more commonly rectangular in cross-section, the mouth being on the narrow side of the pipe.

The gedackt produces a moderately soft, bland, flute-like tone, invaluable for basic ensemble sound in the pipe organ.

Yet, used as a solo voice, the gedackt has a contemplative and relaxing sound in its lower registers, and a singing and plaintive tone in the treble notes.
